The Orioles will add at least three players from Triple-A Norfolk when the rosters expand on Saturday.

Outfielder Xavier Avery, utility man Steve Tolleson and catcher Luis Exposito were all with the team on Friday in New York and will be activated before Saturday's game.

The Orioles will make other additions -- likely among them pitchers Jake Arrieta, Zach Britton and Zach Phillips -- after Norfolk's season ends on Sept. 3. Right-hander Tommy Hunter, now with Double-A Bowie, could also join the team in Toronto.

Left-hander Randy Wolf is also with the team and available to work in relief tonight against the Yankees.
